CUCM Upgrade when one node is unreachable

systempause
Beginner
Beginner

Hello ,

 

We are planning to migrate and upgrade (from vm to vm ) our cucm and imp cluster , we have 3 cucm nodes and 2 imp nodes .

 

But actually 1 cucm and 1 imp server is actually in shutdown state . (we are planning to open these servers later and upgrade them .)

 

You can see our current cucm dbreplication status  as below ;

Can we upgrade cucm and imp cluster in this situation ? And maybe one mounth later we will open powered off nodes and upgrade them also ...

 

BR,

Since you are going to use PCD, cluster discovery will fail for old Cluster. 

 

Your option is to remove the Turned OFF server from cluster and add it later after the migration.

Are you migrating or moving from one Vm to another ?

If migrating, what tool you are planning for migration?

are you planning to use pcd? 

Since the servers are in shutdown and not synced, I don’t think it’s  possible.
